HEIF Converter helps you to convert from HEIC/HEIF/AVIF format to JPEG, PNG and vice versa (convert JPEG, PNG to HEIF/AVIF) without losing any metadata (EXIF...)
It also has the ability to convert media (video, audio) to MP3, FLAC, ALAC, OGG, AAC, AC3... This function also called "Video to MP3" or "Video to audio".

What is HEIF images?
- HEIC is actually a file format used by Apple for storing images on iPhones and Macs.
- The AV1 Image format, or AVIF, is the latest image codec on earth. AVIF is an optimized image format which was created to make our images smaller while keeping the same quality (lossless).

√ Old Android phones prior to P cannot view the HEIF images AND currently Android does not support AVIF image so I have made this application to help user to convert those images to the more popular formats such as JPEG, PNG or WEBP.
